Aggiunge proxy edge con pagina di cortesia e rilascio a downtime minimo.

NPM punta a nginx locale su :3000 che resta attivo durante il restart Rails; nuovo script release_production.sh esegue migrate, build e deploy in ordine.

+|------------|---------------|
+| `edge` (nginx :3000) | Resta sempre su — NPM non vede mai connection refused |
+| Rails in restart | Pagina di cortesia HTML (auto-refresh 15s), non 502 NPM |
+| RTMP :1935 / replay | Non toccati dal rilascio web |
+| `/up` | Pass-through diretto (monitoraggio ops vede il breve gap) |

+Config edge: [`infra/nginx-edge/`](../infra/nginx-edge/). Script: [`scripts/deploy/release_production.sh`](../scripts/deploy/release_production.sh).

 ## Sentry (opzionale)
 
 Imposta `SENTRY_DSN` dopo `bundle install`. Gli errori creano anche incidenti ops.
